P: Creating Directories in Inappropriate Locations ~/Documents

Your understanding of programming error is primitive. 

Can you give me a link where Apple says that applications aren't supposed to write to the Document folder?
https://developer.apple.com/library/content/documentation/FileManagement/Conceptual/FileSystemProgra...

See part About the OS X File System

The preceding directories are for storing user documents and media only. Apps must not write files to the preceding directories unless explicitly directed to do so by the user. The sole exception to this rule is the <i><b>Library</b> </i>directory, which apps may use to store data files needed to support the current user.

Yes, the definition of a bug is that an application crashes or does something faulty, that the programmer clearly did not intended. Bug Definition - The Tech Terms Computer Dictionary . Adobe clearly intended to do this, so it's not a bug.  That doesn't mean it can't be a wrong decision by Adobe, but it's not a bug.

I don't think it violates MacOS architecture. Can you give me a link where Apple says that applications aren't supposed to write to the Document folder? Also remember that Lightroom did this long before Apple suddenly decided to sync the Documents folder with iCloud, so at that time they didn't know that this folder would get synched to iCloud. 

I think it is due to need to support multiple platforms. I agree that Adobe case is not critical to space just annoyances and pollution. Yesterday I tried to install World Of Tanks and it installs 2.5GB into Documents, that was a huge problem.

I hope this case is rudiment which will be eliminated in the future.

I genuinely don't know why they and so many other companies violate Apple's preferences for these things, though perhaps it's simply because Apple changes its mind and they haven't found it worth the resources to change what was once accepted practice??? I find a fairly noticeable percentage of apps I've had for several years use the Documents folder, so at one time, it must have been thought by many to be the right place.

I just looked and I've got Adobe, Foto Magico, DXO, Kaleidoscopes, MagicSquire, MacGourmet, MysticalSuite, etc. All put their folders in Documents with no option during install to put them somewhere else. And they all do have files in other, more expected, locations. But they're in Documents as well.

It just violates macOs architecture. Why don't save system files on Desktop then?

"A bug is when a program does something that it is not intended to do" - Oh really? It is not a bug it is a feature, some developers say when don't want accept errors.

It is not correct behavior because it violates macOS architecture then it is a bug. It store system files in the Cloud. Why don't choose Desktop folder, then? You may trash my desktop and cloud with your system files. If you don't understand that, I have nothing to say then. 

You set your iCloud settings to  sync your entire Documents folder with iCloud? I don't use iCloud except for a few of the Apple products that are listed in its settings folder.

I personally don't think it's a serious bug, although it agree it might be preferable to use one of the Libraries for this sort of file. Other apps, not just Adobe, also use Documents for similar resources, and again, a Library might be a better place for it, but I still don't think it's a serious bug, which would affect our use of the product itself significantly, but a decision they might revisit. It isn't something that would, or ought to, imo, take on a high priority.

LR has enough problems without them spending a lot of limited resources on a folder that, in my case, is 6Kb with 3 versions covered by it. My whole Adobe folder in Documents for all the video apps isn't even very large. A few MB.  Maybe if I did a LOT of video, but then I'd also go in and scrape out all the stuff relating to versions I no longer use, the way I frequently go to the Common folder in my Library and remove all those video files.

A bug is when a program does something that it is not intended to do, so this is not a bug. You may not like it, but that is another matter. And how serious is it really? That folder is a whopping 52 KB on my system...

Lightroom Creates Folder Adobe in Documents folder, which is not correct because it user space and now it syncs with iCloud. I don't want 3rd-party application consumes my cloud storage which is not free.

I think it is a serious bug.

As soon I open Lightroom on my MacBook there is an “Adobe” folder appearing in my “Documents” folder with some “dynamiclinkmediaserver” stuff in it. The Documents folder is obviously the wrong place to put things like that so my question is how to stop it?
